So I went to see a specialist.

I thought to myself a few days ago, "my arm isn't really broken. How can I still get some use out of it if bones are grinding together beneath bruised muscles and cartilage?" Sure it was tender in a couple of places, and I had trouble turning my wrist a few different directions, but no constant pain. Larry (the Ortho Arkansas doctor) said it was just cracked. There is no break all the way through the bone. He said I wouldn't be so happy if it was actually broken, adding, "a broken radius is one of the most painful bones you can break." I am happy to know that I can start bearing weight (up to 20 lbs) on it for the next month. No push-ups and no falling off my bike were his suggestions for a while.
